Dongfeng KR trcuk parts Power socket assembly USB charging 3723020-C5104

Designed to meet the charging needs of multiple electronic devices, the assembly features two USB-A ports with fast-charging technology. Each port supports a maximum output of 5V/2.4A (total 4.8A combined current), enabling quick charging for smartphones (e.g., iPhone, Android devices), tablets, GPS navigators, and dashcams—reducing charging time for a dead smartphone by 40% compared to standard 1A USB ports. The ports are compatible with most charging protocols (QC 2.0, Apple 2.4A, Samsung Adaptive Fast Charging), ensuring compatibility with 95% of consumer electronic devices. Unlike single-port or low-amperage sockets that struggle to charge multiple devices simultaneously, this dual-port design allows drivers and passengers to charge two devices at full speed, critical for long-haul trips where device connectivity is essential

Engineered to prevent electrical hazards in the truck’s cab, the assembly integrates comprehensive safety features. It includes an over-current protection fuse (10A) that automatically cuts power if the current exceeds safe levels (e.g., short circuit from a damaged cable), protecting both the socket and connected devices. The USB ports have built-in over-voltage protection (clamping at 5.6V) and over-temperature protection (shutting down if internal temperature exceeds 60°C), preventing device damage from voltage spikes or overheating. The socket’s internal wiring uses flame-retardant PVC insulation (UL94 V-0 rating) that resists burning in case of electrical faults. Unlike uncertified sockets that pose fire or device damage risks, this assembly meets IEC 62133 safety standards, ensuring reliable, hazard-free operation

Built to withstand the harsh conditions of truck operation—including constant vibration, temperature fluctuations, and daily use—the assembly uses rugged, long-lasting materials. The outer shell is made of scratch-resistant PC (polycarbonate) plastic with a matte finish that resists scuffs from charging cables or accidental impacts, maintaining a clean appearance for years. The USB port connectors are made of gold-plated brass (ensuring low-resistance contact and preventing corrosion) that endures 10,000+ plug/unplug cycles without wear. The internal circuit board is coated with a conformal epoxy layer (0.15mm thickness) that protects components from dust, moisture, and electrical interference—ensuring reliable operation in humid or dusty cab environments. Unlike cheap plastic sockets that crack or fail within 6 months, this durable design operates reliably for 3+ years

Designed for driver convenience and simple replacement, the assembly features a user-friendly layout and hassle-free installation. The USB ports are angled at 15° upward for easy cable insertion, even in low-light conditions, and are labeled with clear “Fast Charge” icons for quick identification. The socket has a built-in LED indicator (soft blue light) that illuminates when power is connected, helping users locate the ports at night without distracting from driving. For installation, the assembly includes all necessary hardware: a mounting nut, lock washer, and a 30cm extension wire (if needed) that connects to the cab’s original electrical harness. No specialized tools are required—installation takes 15–20 minutes: insert the socket into the mounting hole, secure with the nut, and plug in the wiring connector. Each unit undergoes strict testing: vibration testing (10–2,000 Hz), temperature cycling (-40°C to 85°C), and charging performance verification. Backed by a 12-month warranty against manufacturing defects (e.g., port failure, fuse burnout, shell cracking), it provides Dongfeng KR truck owners with a reliable, convenient charging solution
